Scientists discover batteries recharging in seconds

Scientists at MIT have developed a new design for lithium batteries that could cut recharge times down to seconds. Traditional lithium batteries dispense power slowly, but also charge slowly because of perceived limitations in the lithium itself. However, the team at MIT found that the problem lies not in the lithium, but in the substrate around it, according to a paper (PDF) published in Nature. The team, led by Gerbrand Ceder, the Richard P. Simmons Professor of Materials Science and Engineering at MIT, and Byoungwoo Kang, a graduate student in materials science and engineering, has created a battery that can be fully charged and discharged in under 20 seconds.

The ability to charge and discharge batteries in a matter of seconds rather than hours may open up new technological applications and induce lifestyle changes, Ceder and Kang concluded in the paper. The team believe that the new technology could be available in two or three years, because it is based around the commonly used lithium battery.

now this be the next technology, nice find

Looking good for the auto industry, maybe.

I bet they CHARGE a fortune, wayhey!!!

The register isn't very impressed:
They say that other better technologies are already in development.

Supercapacitors have existed for a few years and they essentially do the same thing (although probably leak more and store less per weight/area than the new lithium design). New battery technologies are always promising though...

if I read that right, it'll take a few seconds to recharge which is great, but also a few seconds to discharge which is not so great!

I was just thinking the same! It would make having a battery operated car much more viable!

You're thinking of it wrong, they will only drain as fast as what ever demand is put on them. Say a car needs to accelerate really fast to get out of a dangerous situation then the power will be there immediately. If it's accelerating to 50mph in 20 seconds though it will last a lot longer
